Formaldehyde emissions from conventional particleboards raise issues of health and safety. One of the potential solutions is binderless particleboards made without using synthetic adhesives. However, the physical and mechanical properties of untreated binderless particleboards are relatively poor compared to conventional particleboards. This research aims to reveal the potential of using steam pretreatment to improve binderless particleboard properties made from oil palm trunk. The oil palm trunk particles were treated with steam pretreatment for different durations of time (20, 40, 60 min). The chemical constituents of the treated and untreated particles were evaluated. The binderless particleboards were made from treated and untreated particles. In addition, panels using untreated oil palm trunk particles with 10% urea–formaldehyde resin were made and used as a comparison. The boards were evaluated according to European Standards. The results indicated that the hemicellulose and starch content gradually reduced with the progression of steam pretreatment. The physical and mechanical properties were improved by increasing steam pretreatment duration. The steam pretreatment was able to improve the properties of binderless particleboards made from oil palm trunk. However, the performance of steam-pretreated binderless particleboard in this study is not compatible with the particleboards made using 10% urea–formaldehyde.

Oil palm frond pulp (OPF) was blended with activated carbon for the purpose of active packaging in this preliminary study. It was aimed to investigate the effect of in-situ activated carbon on physical and mechanical properties of the pulp handsheets made from OPF. Testing of property performances of the resulted handsheets included density, moisture content, thickness swelling, folding, tensile strength, %elongation, stiffness, and modulus of rupture. Ultimately, the intention is to use for prospected active packaging for fresh produce. OPF pulp was prepared by the kraft process. The pulp stock was mixed with different proportions of activated carbon (0, 10, 20, and 30% w/w). The results showed that an increased proportion of activated carbon decreased density and thickness selling, but had no effect on moisture content.

One of the natural fiber considered to replace syntetic fiber is Oil Palm Empty Fruit Bunches (OPEFB) fiber which offer advantages such as environment friendly and widely available especially in indonesia . This study investigates the characteristics of railway brake block with OPEFB fibres compare to synthetic fiber. All the test results were compared to the technical requirement of PT. Kereta Api Indonesia (PT. KAI ) and evaluated using Extension Evaluation Method (EEM) to select and get the best sample. From the evaluation results using EEM, one of non commercial sample using OPEFB fiber give a better results compare to commercial sample using synthetic fibers. So it can be concluded that OPEFB fiber as reinforcement for railway brake material could improve physical and mechanical properties of the material, environment friendly and could replace synthetic fibers.

The aim of this study was to determine the physical and mechanical properties of Cross laminated timber (CLT) made from oil palm (Elaeis guineensis. Jacq) stem waste combined with thinned platinum teak (Tectona grandis ) wood. CLT was made into two types, namely CLT type A (teak-palm-teak) and CLT type B (teak-teak-teak). The CLT was 150 cm in length and 20 cm in width, with variation of the thickness of 3,0 cm, 4,5 cm, and 6,0 cm, and the glue spread of 300 g/m². The results showed that CLT type B has better physical and mechanical properties than CLT type A. Generally, CLT made of lamina with a thickness of 4,5 cm showed the best performance of physical and mechanical properties. Platinum teak and palm oil stem waste have the potential to be used as a source of CLT raw materials because of the moisture content, flexural modulus (MOE), and fracture modulus (MOR) that meet the JAS 1152 standard.Keywords: Cross laminated timber, platinum teak, oil palm stem, physical properties, mechanical properties

The physical and mechanical properties of Rubber wood, Acacia wood, and Oil palm wood that reacted with acetic, propionic, and butyric anhydrides using a microwave heating for 4 minutes were investigated. A sample dimension of 300 mm × 100 mm × 25 mm (L×W×T) was used for modification and they were cut into smaller specimens for different testing method. This study found that the density increment and void volume changes were not significantly different from anhydrides. The modification of wood with anhydrides was not significantly affected by the static bending properties, except for the Oil palm. The compression strength for any anhydrides shows an improvement for the Rubber wood and Acacia spp. but not Oil palm. The hardness was also not significantly different from anhydrides for all wood species. The impact strength of Rubber wood and Oil palm significantly increased compared to the untreated wood, but this was not the case for Acacia spp. Generally, the highest improvement in mechanical properties was obtained by modification of Rubber and Acacia woods with butyric anhydride.
